Custom cursors

[FlashAahaah]

I have added a custom cursor to my application, using the following code:

Mouse.hide();
mouseEnabled = false;
stage.addEventListener(MouseEvent.MOUSE_MOVE,follow);
function follow(evt:MouseEvent)
{
	cursor.x = mouseX;
	cursor.y = mouseY;
}

However it does not stay on top of the scene because new objects are created during the application run, and the cursor goes behind them as it is an older object. I want the cursor to stay on top at all times... How can I do this?
